Stainless steel is the hardest of the three and the most water-resistant; sterling silver carries the most precious-metal content for the least money but tarnishes; white gold sits between them as a gold alloy finished with rhodium plating. Which one suits you depends on whether you want low-maintenance daily wear, real precious-metal content, or the traditional cool-white finish used in fine jewellery.

All three turn up described as "white metal" jewellery, and a plated piece in any of them can look identical at a glance. What is underneath the finish is where they stop being interchangeable.

What is sterling silver, and how hard is it?

Sterling silver is 92.5% pure silver alloyed with 7.5% copper. Pure silver alone is too soft for jewellery — about 2.5 on the Mohs scale, similar to a fingernail — so copper brings the alloy up to roughly 2.5 to 3 without changing the colour much. We cover the 925 stamp itself in is 925 sterling silver real silver.

That same copper is why sterling silver tarnishes: it reacts with sulfur compounds in the air and forms a thin film of silver sulfide, a surface reaction that polishes off rather than lasting damage. Copper is also behind the faint skin marking some wearers see, covered in will sterling silver turn my finger green. Most sterling silver we sell is rhodium-plated, which is harder and brighter than silver and keeps a piece looking sharp with less upkeep — not indefinitely, since any plating wears with contact.

What is white gold, and does it turn yellow?

White gold is gold alloyed with a white metal, usually nickel, palladium or manganese, to dilute its natural colour. Karat sets the gold content — 10k is 41.7% gold, 14k is 58.3%, 18k is 75% — and the rest is the whitening alloy, which on its own is a faint grey or champagne tone, not bright white. That is why nearly every piece of white gold sold is finished with rhodium plating, the same metal used to finish sterling silver.

Gold itself does not tarnish; it is a noble metal and does not react with air or moisture. What people call white gold "turning yellow" is the rhodium plating wearing thin at points of contact, letting the alloy's warmer tone show through — not the gold oxidising. Replating restores the white finish, the same mechanism we describe for silver in does rhodium plating wear off, and how long does it last.

One thing worth being plain about: we do not currently sell solid white gold. What reads as a white-gold finish in our own range is rhodium-plated 925 sterling silver, like the eternity band, or stainless steel in a white-gold-tone plating, like the layered necklace set below. Both carry the same cool-white surface a jeweller would put on solid white gold, with no gold alloy underneath — worth knowing before you shop anywhere, not just with us.

What is stainless steel, and why does it resist tarnish?

Jewellery-grade stainless steel is usually 316L, sometimes called "surgical steel": an iron-chromium alloy, roughly 16–18% chromium and 10–14% nickel, with added molybdenum for corrosion resistance and a low carbon content. On the Mohs scale it runs about 5.5 to 6.5, several times harder than sterling silver or a gold alloy, so it shrugs off knocks that scratch softer metals.

Chromium does the work against tarnish, forming a thin, self-healing oxide layer that keeps resisting corrosion after years of contact with skin, sweat and water — the property behind pieces like our Miami cuban link bracelet and cross charm bracelet. 316L does contain nickel, but it is locked tightly in the alloy's structure and releases at very low rates, which is why it is widely treated as hypoallergenic under the EU's EN 1811 standard. Our four-piece bracelet set is listed nickel-free on that basis.

Sterling silver vs white gold vs stainless steel, at a glance

Property Sterling silver White gold Stainless steel
Composition 92.5% silver, 7.5% copper Gold alloy (10k–18k) with nickel, palladium or manganese Iron-chromium alloy, ~16–18% chromium (316L)
Mohs hardness 2.5–3 Roughly 2.5–4, by karat 5.5–6.5
Tarnishes? Yes — copper reacts with sulfur in air No, but the rhodium finish wears and the alloy can show Rarely — self-healing oxide layer
Usual finish Often rhodium-plated Almost always rhodium-plated Bare polish, or gold/rhodium plating
Water and chlorine Tolerates water; soap film dulls it Best removed for swimming Handles water and chlorine well
Cost tier Entry-level precious metal Fine-jewellery, priced on gold content Most affordable, everyday tier
Best suited to Precious metal without gold pricing Gold content in a cool-white finish Low-maintenance daily wear

Which is the most durable for daily wear?

On hardness alone, stainless steel wins clearly: roughly 5.5 to 6.5 on the Mohs scale against under 4 for sterling silver or a gold alloy. That is why our waterproof gold bangle and stacking ring use a stainless steel or titanium core under gold plating rather than solid gold — the core survives daily contact, the plating supplies colour.

Rhodium plating narrows the gap while it lasts, since rhodium is hard and bright, but that fades as the plating wears at points of contact — prongs, the underside of a ring, a clasp — over months to a few years. Stainless steel does not depend on a surface layer for its hardness, the practical difference for a piece you rarely take off.

Which is safest for sensitive skin?

Sterling silver's risk is copper, not silver: on more acidic skin it can leave a faint dark or greenish mark, a chemical reaction rather than an allergy (see will sterling silver turn my finger green). White gold and stainless steel both commonly contain nickel, the more familiar allergen — closer to the surface in white gold once rhodium wears, but bound tightly enough in 316L that release rates stay low. Anyone with a known, severe nickel allergy should still look for pieces explicitly listed nickel-free rather than trusting "stainless steel" alone.

Which should you actually choose?

For low maintenance — showers, workouts, wearing it every day without a second thought — stainless steel is the honest answer. For precious-metal content at an accessible price, sterling silver is real silver, stamped as such, and needs only occasional cleaning and eventual attention to its rhodium finish. For a gold-based piece with a cool-white finish, that is what white gold is built for — but budget for replating over the years, and confirm with any seller whether you are buying a solid alloy or a plated finish made to look like one.

Common questions

Which is stronger, sterling silver, white gold or stainless steel?

Stainless steel, by a wide margin, at roughly 5.5 to 6.5 on the Mohs scale against 2.5 to 3 for sterling silver and roughly 2.5 to 4 for white gold. Rhodium plating adds surface hardness to silver and white gold while it lasts, but the base alloys remain softer.

Does white gold eventually turn yellow?

The gold itself does not tarnish. The rhodium plating on top wears thin at points of contact, letting the warmer alloy underneath show through, and replating restores the white finish.

Is stainless steel jewellery "real" jewellery, or costume jewellery?

Stainless steel is a genuine, durable alloy chosen for its hardness and corrosion resistance. It sits at a lower cost tier because it contains no precious metal, not because it is lower quality.

Can you shower or swim in sterling silver, white gold or stainless steel?

Stainless steel handles water, sweat and chlorine best of the three. Sterling silver tolerates plain water but soap film and chlorine dull it faster, and white gold's rhodium plating is also best kept away from chlorine. More detail in can you shower or swim in sterling silver.

Is stainless steel jewellery hypoallergenic?

316L is widely treated as hypoallergenic because its nickel is bound tightly in the alloy and releases at very low rates, meeting the EU's EN 1811 standard. It is not an absolute guarantee for every allergy, which is why some pieces are separately listed nickel-free.

Which piece should you start with?

If low maintenance matters most, start with something entirely stainless steel, like the stainless steel bracelet set or the Miami cuban link bracelet, both fine straight into a shower. For a genuine precious-metal piece, the moissanite tennis bracelet or the eternity band are 925 silver with the same rhodium finish used on solid white gold, which we do not currently sell. If solid white gold is specifically what you want, ask any seller directly whether you are buying a solid alloy or a plated finish, and use the figures above to check what you are told.
